A week age my GOLF SV battery ran down after using the radio for too long while parked.
Car was jump started by roadside assistance, but ever since then it has been losing charge overnight.
Suspected battery may be near end of life so replaced with new, a correctly spec'd Bosch AGM.
But no change. Still going flat when parked for more that one day.
Tested for parasitic draw and found the MIB2 infotainment system is drawing 1.2A to 1.5A even when the car is switched off and locked.
And this draw is continuous. Doesn't stop after a period of time.
Battery state of charge drops to 50% over one night, but increases to 95% after engine running for an hour or so so clearly no problem with charging system.
This has only been happening since the jump start.
Can anyone explain what may have changed and what I can do to fix it.
